Prevention of Plantar Fasciitis
Relax, relax, relax. Learn to relax your lower legs, especially your ankles and calves, whenever you're walking, running, sitting or standing. Tension held anywhere in your legs or glutes will pull on the Plantar tendon when you move.

Land with a midfoot strike. Land evenly on the middle of your foot instead of heel striking. This keeps your Plantar tendon relaxed and reduces the impact to your heels.

Don't pull yourself forward with your legs when walking or running. Engage gravity by letting your upper body lead and your legs follow. Throughout your runs, lean slightly from the ankles, keep your stride short, and land with your feet directly under your center of mass.
